The basics

A Fiserv statement, read in the order that finds the money.

These statements are long because they itemise interchange, and that is a feature rather than a problem. The trick is knowing that the summary page is the least useful one and reading it backwards.

What this page settles.

Three questions, in the order most people ask them.

01Page oneDesigned to reassure. Read it last.
02The middleFee summary. Add it all up.
03The backInterchange detail. The real story.

Why these statements are long

A Fiserv or First Data statement commonly runs several pages, and merchants treat that as evidence of obfuscation. It is usually the opposite.

The length comes from itemising interchange — listing, category by category, how many transactions fell into each of the networks’ interchange tiers and what each tier cost. There are dozens of categories. A statement that shows them is a statement you can audit.

The statements that are genuinely hard to read are the short ones, where everything is collapsed into a single blended rate and interchange appears nowhere. You cannot tell from those whether a transaction downgraded, whether your card mix shifted, or whether an April interchange update affected you. Blended pricing.

So the length is not the problem. Reading it front to back is. Page one is a summary designed to be reassuring, and the useful part is at the back.

One caveat before the specifics: layouts vary by ISO, by platform generation and over time. What follows is the structure these statements share, not a guarantee about your page numbering.

What each section is for

The deposit or funding summary. What you processed and what was deposited, usually with a daily breakdown. This is where you confirm that the money arriving matches the money you took, less fees. If your arrangement is daily discount, every deposit is net of fees and nothing will match your sales. Daily versus monthly discount.

The card-type summary. Volume and transaction count split by Visa, Mastercard, Amex, Discover and debit. Useful for one thing above all: working out your debit share, which decides whether a flat rate is treating you well. Debit versus credit cost.

The fee summary. Every charge for the month. Discount or processing fees, authorization fees, the per-item charges, and the monthly fixed fees — statement fee, monthly minimum, PCI program fee, PCI non-compliance fee, annual fee, batch fees, gateway fee. This is the page people skip and it is where the avoidable money is.

The interchange detail. Several pages of category codes with counts, volume and cost for each. This is the section that tells you what actually happened to your transactions.

Adjustments and chargebacks. Reversals, retrievals, chargebacks and their fees.

The ten-minute read

Four numbers, in this order. You need a calculator and nothing else.

One: total card volume for the month. Usually on the summary page.

Two: total fees for the month. Add every charge, including the fixed monthly ones. If there is a “total fees” line, check it actually includes the monthly items rather than just the discount.

Three: divide two by one. That is your effective rate, and it is the only figure comparable to anything — to a quote, to last month, to a competitor’s published rate. It will not be printed anywhere on the statement. The calculator does it from those two figures.

Four: your transaction count, divided into volume. That is your average ticket, and it tells you whether the per-item fees matter to you. Under $20, they dominate. Over $100, they are noise.

Write all four down somewhere you will find them next month. Comparing them month to month is how you notice a change in week two instead of year two. Why the bill went up.

The lines that cost the most

Now go to the interchange detail and look for three things.

Downgrade categories. Anything described as non-qualified, standard, EIRF, or a commercial or business category where you were not expecting commercial cards. Each of those is a transaction that failed to qualify for the tier it should have, at a surcharge typically between half a percent and a full percent. Count the volume sitting in them. On $48,500 of volume, $408.50 of downgrade surcharges is a quarter of the whole bill. Non-qualified surcharges.

Card-not-present categories on a card-present business. If you run a counter and a meaningful share of your volume is in card-not-present tiers, somebody is keying cards that could be tapped. Card-not-present downgrades.

Commercial card volume without the data. Business and corporate cards carry much higher interchange, and much lower interchange when the transaction includes the extra fields. If you do work for other businesses, this is the single biggest lever available. Level 2 and Level 3 data.

Then go back to the fee summary and look for the four avoidable fixed charges: a PCI non-compliance fee, a monthly minimum you are missing, a gateway fee for a gateway you do not use or already pay for elsewhere, and a regulatory compliance fee, which is not a regulation.

Pricing models you may be on

The statement tells you which, if you know what to look for.

Interchange-plus. Interchange is itemised and the markup appears as a separate, consistent percentage and per-item. This is the arrangement you want, and the one where the detail pages are genuinely useful. Interchange-plus pricing.

Tiered. Volume is grouped into qualified, mid-qualified and non-qualified, each at its own rate, and interchange is not shown separately. The quoted rate was the qualified tier only, which is why the rate you were quoted and the rate you pay differ. Non-qualified surcharges.

Enhanced billback. A low rate is charged at the time of the sale and the rest arrives weeks later as a separate adjustment line, often on the following month’s statement. If you see an adjustment referring to a prior month’s volume, this is what it is — and the two months together are what the arrangement actually costs. Enhanced billback.

Flat or blended. One rate, no interchange shown. Simple, and unauditable. Blended pricing.

What to ask about

Having read it, five questions for whoever services your account. They are reasonable questions and the quality of the answers tells you something.

“What is my effective rate, and what was it three months ago?”

“What proportion of my transactions downgraded last month, and why?” A good answer names the categories.

“What is this fee for?” — for every fixed monthly charge you cannot explain.

“Am I on interchange-plus, tiered or billback?” If the answer is vague, you are on one of the last two.

“What would interchange-plus cost me?” If you are not already on it and your volume is above roughly $12,000 a month, this is the question with the most money in it. Comparing two quotes.

What we charge

Interchange + 0.50% + 10¢ in person, interchange + 0.75% + 25¢ keyed, with no contract, no monthly fee and no monthly minimum.

If you would rather not do the ten-minute read, send us one page and we will do it — your effective rate, every fee named, and which transactions downgraded. We do it free because a merchant who understands their statement is a better merchant to have, including when they decide to stay where they are.

While we are on the subject

Why is my Fiserv statement so long?

Because it itemises interchange by category, which is dozens of lines. That length is a feature — a short statement is usually one that has hidden interchange inside a blended rate.

Where is my actual rate on the statement?

It is not printed anywhere. Divide total fees by total card volume yourself; that figure is your effective rate and it is the only one that means anything.

What are the three-letter codes in the interchange section?

Interchange category abbreviations set by the card networks. Each one is a tier with its own rate, and the expensive ones are the downgrade categories.

My statement looks nothing like this. Why?

Layouts vary by ISO, by platform generation and over time. The structure below is what they share; the page numbers and headings will differ.
